BACKGROUND OF THE INVENTION

1. Technical Field

This invention relates in general to computer accessories and, more particularly, to a lap desk for a mobile computer.

2. Description of the Related Art

Mobile computers now account for almost half of all computer sales. Mobile computers now have the computing power and functionality of a desktop computer and provide the additional functionality of providing computing power wherever desired.

Many mobile computer users place the mobile computer on their laps during a computing session. This placement of the computer has several disadvantages. First, mobile computers often have air vents in the back and placing the computer on a soft surface (such as a bed, pillow, couch or user's lap) can partially of fully block those vents, resulting in overheating of the internal components. Second, a mobile computer can generate a significant amount of heat at its bottom surface, which can cause user discomfort. Third, user of some peripherals, such as a mouse, is difficult while the user is in a sitting position.

Accordingly, many users have purchased lap desks for placing between the user's lap and the mobile computer. Typical lap desks provide a flat surface for the mobile computer, some having additional space to operate a mouse on the side. Beyond that, they offer very little functionality.

Therefore a need has arisen for a mobile computing desk with added functionality for users.

BRIEF SUMMARY OF THE INVENTION

In the present invention, a computer lap desk includes a body portion having an upper surface for supporting a mobile computing device, with the body portion having a first attachment means. One or more accessories each have second attachment means for engaging with the first attachment means to secure the accessory to the body portion.

The present invention provides flexibility to a user to design a mobile computing desk top that suits the needs of the user. By providing interchangeable accessory devices, the user can change the configuration of the desk as desired.

Tabs 18 rotate upward (see magnified view) to hold the computer at a better angle for typing and to provide additional airspace for the fans of the mobile computer. An armrest 20 provides comfort and stability to the user's wrists while typing.

Slots 22 are formed into the lap desk 10 at both sides of the top surface 12. Slots 22 have a bottom surface 24 (best shown in FIG. 2 c). The slots 22 align with tabs 25 on various accessory devices 26, described below. FIG. 1 illustrates a mouse tray 28 which mounts onto lap desk 10 using slots 22 to provide an additional surface to the lap desk 10 for using a mouse or similar device. The slots 22 on the lap desk 10 and the tabs 25 on an accessory device are arranged in a symmetrical manner to allow accessory devices 26 to be attached to either side of the lap desk 10.

The bottom surface 30 of the lap desk, shown in FIG. 2 b, includes leg rests 32 to raise the desk off of a user's lap to further remove the user from heat generated by the mobile computer. The leg rests 32 also have a non-slip surface to prevent the lap desk from slipping off of the user's lap. Storage space 34, including slots 36 and clip 38, is used to store an accessory device underneath the lap desk 10 for storage and travel.

In operation, the user may snap one or two accessory devices onto the sides of the lap desk (more accessory slots could be provided on the lap desk 10 to hold even more accessory devices). The user may exchange the accessory devices as desired. Since the accessory devices are not fixedly integrated with the lap desk, the user can purchase any desired configuration of devices.

While not shown, the desk 10 could include a subset of the following devices: storage compartments for paper clips/office supplies, pens and pencils, mobile phone/PDA (personal digital assistant), screen wiping pads, business cards, eye glasses, batteries, cables, business cards, and business receipts/miscellaneous papers. The compartments could be drawers which slide out of the desk, or cavities formed in the top surface 12.

In addition, the desk 10 could incorporate active devices used in connection with the mobile computer. For example, the desk 10 could include an integrated USB (Universal Serial Bus), Firewire, or other connection type, hub for providing data connections to a plurality of devices. Also, a memory reader for reading a plurality of memory types, such as FLASH memory, could be built into the desk. Also, the desk 10 could include an auxiliary battery for the mobile computer, similar to universal rechargeable battery types which provide a DC input to the mobile computer at a selected voltage level and polarity configuration.

For additional user comfort, the arm rest support 20 could include an imbedded magnet to help blood circulation in the user's wrist to alleviate fatigue while typing. A warming pad could be provided for warming cold hands. A personal aroma therapy pad could provide relaxing or stimulating aromas.

FIG. 3 illustrates a numeric keypad accessory device 40. The keypad device 40 uses a USB (Universal Serial Bus) connection 42, or other suitable connection, to interface with the mobile computer.
